DEFLECTING SHADE FOR HEADLIGHTS.

Application led February 7, 1927. Serial No. 166,554.

This invention relates to improvements in lamps and is especiallyadapted for use in connection with the head lamps of automobiles.

An object of the presentr invention is the provision of a shield adaptedto be arranged within a lamp casing and capable of movement toward andaway from the lamp, so that the latter may be used to direct the rays oflight an appreciable distance in advance of a vehicle, or to interceptthe rays of light. l

Another object of the invention is the provision oi"- novel means formoving the shield into and out of position and for supporting saidshield within the lamp casing.

lVith the above and otherl objects in view, the invention furtherincludes the following novel features and details of construction,

to be hereinafter more fully described, illus.

trated in the accompanying drawings and pointed out in the appendedclaim.

In the drawings Figure 1 is a front view of a lamp equipped with theinvention with the shield closed in normal position.

Figure 2 is a similar view showing the shield in use.

Figure 3 is an enlarged section taken substantially on the line 3 3 ofFigure 1.

Figure 4 is a detail view of the shield operating mechanism.

Referring to the drawings in detail wherein like characters or referencedenote corresponding parts, the reference character 10 indicates thecasing of a lamp of the type used for vehicle head lamps. The lampincludes a reflector 11 and a lamp socket 12. Any suitable means may beprovided for mounting the socket 12, the'nieans shown consisting ofattaching the socket to a substantially L-shaped bracket 13 and mountingthe latter so that the socket may be moved axially. For this purposethere is provided a bolt 14 which extends into the lamp casing and uponwhich is mounted a spring 15. This spring acts to urge the socket towardthe front of the lamp, while adjustment may be effected to focuse thelamp by operating the screw.

Mounted for swinging movement within the lamp is a shield 16 and inorder to pivotally support the shield there are provided spaced bearingarms 17. Thev inner ends of these arms are clamped or otherwise secured55 to the socket 12 as indicated at18 and the arms extend laterally,forwardly and upwardly and terminate in bearings 19. These bearings arearranged above and in advance of a lamp 20 positioned within the socket12'. 00 The shield 16 is provided with oppositely extending pintles 21which are mounted within the bearings 19 and secured to one of lthesepintles is a toothed wheel 22. Mounted Within the lamp casing is asolenoid 23 whose core 24 is extended and provided with teeth 25 whichengage the toothed wheel 22. The solenoid receives current from abattery B or other source through conductor wires 26 and current to thesolenoid is eon- 7 trolled by a switch 27.

Normally, the parts are arranged as shown in Figures 1 and 3, the spring28 being connected to the core 24 so as to yieldingly hold the shieldelevated. When the switch 27 is closed to complete ia circuit throughthe solenoid, the core 24 will be drawn upward to rotate the Wheel 22and cause the shield '16 to swing downward in front of the lamp 20. Therays from the lamp 20 may thus be used to illuminate the roadway inadvance of the lamp, or these rays may be intercepted to prevent theglare from causing confusion to persons approaching the lamp.

Vhile the invention is shown applied to a single lamp, a pair of lampsmay be connected so that the shields will operate synchronously, or eachone of a pair of lamps may be equipped with the invention and arpositesides of the socket, means mounted upon the socket and connectingtheinner ends of the arms to support said arms, bean ings at the outer endsof the arms, a shield positioned between the arms and having pntesmounted in said bearings, a toothed Wheel secured to one of the pintles,2L solenoid having n toothed core engaging the Wheel to swing the shielddownward when the so1e-l noid is energized and means to move the shieldto e normally eevzited position.
